Summer Work in Preparation for Seismic Upgrade

SFPUC anticipates awarding this Seismic Upgrade Project contract within 45 days.Once we have Commission approval, another public meeting will take place later this summer to provide you with information on the upcoming project as well as an opportunity to meet the Contractor.

Two relocation projects need to be completed before the Seismic Upgrade of Bay Division Pipeline Nos. 3&4 can begin. Alameda County Water District water line just completed their project. Union Sanitary District (USD) sewer pipelines cross theHetch Hetchy Right of Way where the Seismic Upgrade will be installed later this Fall.

Projected Timeline:

·Summer 2012 - Union Sanitary District utility relocation and Alameda County Water District water line tie in.

·Fall 2012 - Seismic Upgrade Project construction begins

·Winter 2014 - Expected completion of the project

USD awarded the Sanitary Sewer Relocation Project last month to K.J. Woods Construction Inc.Mobilization to the site is scheduled to begin early May.The Contractor estimates project completion in August.

Here is the USD Project Area:

Starting this week, USD’s Contractor will begin mobilizing to the project site. They will install the environmental exclusion fencing around the construction site, potholing for utilities and constructing the temporary road to the project area.

Please see below for the construction notice that was mailed out to adjacent neighbors. In addition, USD’s Contractor will issue notices to neighbors near the project site.

We will continue to update our blog as more information about this project becomes available.

Are you Prepared for the next Earthquake?

The Hetch Hetchy regional water delivery system is taking steps to seismically reinforce its pipelines, tunnels and other facilities and we encourage you to be PREPARED. Check with your County or 72hours.org about how you can get ready. Remember, store at least a gallon of water per person, per day—enough to last 3 days, for drinking, cooking and personal hygiene—and don’t forget your pets.

Project Information

The Seismic Upgrade of Bay Division Pipelines Nos. 3 and 4 (BDPL 3&4 Seismic) is part of the San Francisco Public Utilities Commission’s Water System Improvement Program. This project will seismically upgrade two drinking water pipelines where they cross the Hayward Fault in Fremont. To protect the water system, the BDPL 3&4 Seismic project is replacing large sections of the pipelines with high-tech pipe elements and structures designed to protect them from damage during a major earthquake.

The pipelines, known as Bay Division Pipeline Nos. 3 and 4, cross the Hayward Fault near the intersection of Mission Boulevard and I-680 in Fremont. All project work will take place within the SFPUC’s right of way and nearby staging areas.

The seismic upgrade of Bay Division Pipeline Nos. 3 and 4 will improve the reliability of the water system for the Hetch Hetchy Regional Water System’s 2.6 million customers in the Bay Area, including Alameda County.

Our project team is working closely with local officials to ensure construction schedules are timely and traffic and community inconveniences are minimized.

Our Goal

It is our goal to provide timely, useful information on the Seismic Upgrade of Bay Division Pipeline Nos. 3 and 4 throughout the duration of the project. As construction continues, check back for construction updates, work schedules and traffic impacts in Fremont.
